I learned a few things about photographing flowers when I created my Casablanca Lily photos, and I used that knowledge when making these photos of sunflowers. First, I maximized my depth of field on close-ups by setting the aperture to f/10 and smaller.^[1]The same aperture on a medium format camera does not produce an equivalent depth of field on a 35mm camera. The crop factor used to determine equivalent focal length can also be used to calculate aperture equivalence (and therefore depth of field). An aperture of f/10 on a 6×6 TLR with an 80mm lens is equivalent to f/5.5 on a 35mm (full frame) camera with a 44mm focal length. You can calculate your own aperture and focal length values using this crop factor calculator. This helped to keep all parts of the flower in focus. Second, I used an LED light panel instead of studio strobes so that I could better control shadows. While not perfect, it did make a difference in reducing unwanted shadows. In retrospect, I think next time I will light the background separately to create a completely shadow-free background.
